League of Women Voters of Massachusetts v. Trump
On March 31, 2026, President Trump issued a sweeping Executive Order titled "Ensuring Citizen Verification and Integrity in Federal Elections," seeking once again to seize control of election administration from Congress and the states. The Order directs federal agencies to compile lists of U.S. citizens and transmit them to states before every election, directs the U.S. Postal Service -- an independent agency established by Congress -- to create a list of "approved" mail voters, and instructs USPS to refuse to deliver ballots from voters not on that federally created list. If implemented, the Order would threaten the ability of millions of eligible citizens to cast their ballots, particularly military members, overseas citizens, the elderly, recently naturalized citizens, and voters with disabilities who rely on mail voting.

Barbara v. Donald J. Trump
President Trump is attempting to undermine the promise of birthright citizenship to children born on U.S. soil. But the ACLU and partners are fighting to protect the rights of citizens that are plainly stated in the Constitution, federal statute, and reaffirmed by the Supreme Court for more than a century. We’re arguing against the Trump administration in the Supreme Court and are confident we will win.

Wise v. Missouri
In unprecedented fashion, the State of Missouri has redrawn the district lines used for electing members of Congress for a second time this decade. These new district lines are gerrymandered and will harm political representation for all Missourians, particularly Black residents in Kansas City, who have been divided along racial lines.

White v. Mississippi State Board of Elections
District lines used to elect Mississippi’s Supreme Court have gone unchanged for more than 35 years. We’re suing because the current lines crack the Mississippi Delta and dilute the voting strength of Black Mississippians in state Supreme Court elections, in violation of the Voting Rights Act.

FOIA Case Seeking the Trump Administration’s Legal Justification for Deadly Boat Strikes
The Department of Justice’s Office of Legal Counsel (“OLC”) authored a legal opinion that reportedly claims to justify the Trump administration’s illegal lethal strikes on civilians in boats in the Caribbean Sea and eastern Pacific Ocean. Media reports indicate that, in addition to claiming that the strikes are lawful acts in an alleged “armed conflict” with unspecified drug cartels, the OLC opinion also purports to immunize personnel who authorized or took part in the strikes from future criminal prosecution. Because the public deserves to know how our government is justifying these illegal strikes, and why they think the people who carried them out should not be held accountable, the ACLU is seeking immediate release of the OLC legal opinion and related documents pursuant to the Freedom of Information Act.

Racial Justice
Allen v. Milligan
Whether Alabama’s congressional districts violate Section 2 of the Voting Rights Act because they discriminate against Black voters. We succeeded in winning a new map for 2024 elections which, for the first time, has two congressional district that provide Black voters a fair opportunity to elect candidates of their choosing despite multiple attempts by Alabama to stop us at the Supreme Court. Despite this win, Alabama is still defending its discriminatory map, and a trial was held in February 2025 to determine the map for the rest of the decade.
In May 2025, a federal court ruled that Alabama's 2023 congressional map both violates Section 2 of the Voting Rights Act and was enacted by the Alabama Legislature with racially discriminatory intent.

League of Women Voters Education Fund v. Trump
On March 25, 2025, in a sweeping and unprecedented Executive Order, President Trump attempted to usurp the power to regulate federal elections from Congress and the States. Among other things, the Executive Order directs the Election Assistance Commission—an agency that Congress specifically established to be bipartisan and independent—to require voters to show a passport or other citizenship documentation in order to register to vote in federal elections. If implemented, the Executive Order would threaten the ability of millions of eligible Americans to register and vote and upend the administration of federal elections.
On behalf of leading voter registration organizations and advocacy organizations, the ACLU and co-counsel filed a lawsuit to block the Executive Order as an unconstitutional power grab.

State Board of Election Commissioners v. Mississippi State Conference of the NAACP
Mississippi has a growing Black population, which is already the largest Black population percentage of any state in the country. Yet. Black Mississippians continue to be significantly under-represented in the state legislature, as Mississippi’s latest districting maps fail to reflect the reality of the state’s changing demographics. During the 2022 redistricting process, the Mississippi legislature refused to create any new districts where Black voters have a chance to elect their preferred representative. The current district lines therefore dilute the voting power of Black Mississippians and continue to deprive them of political representation that is responsive to their needs and concerns, including severe disparities in education and healthcare.

ACLU FOIA Suit for ICE’s Updated Solitary Confinement Policy
ICE’s use of special management units, or solitary confinement, has prompted active concern and attention from Congress, the media, and advocates. On Dec. 6, 2024, ICE announced that it had issued policy updates for the use of special management units (SMU), or solitary confinement cells, for detained immigrants. ICE, however, has not made a copy of the updated policy publicly available. We’ve sued to obtain a copy of this policy to better defend immigrants subject to solitary confinement in detention.

Prisoners' Rights
Huskey v. Oregon Department of Corrections
This case in the Oregon Supreme Court centers on whether Article I, Section 41(3) of the Oregon Constitution, which provides that Oregon prisoners lack legally enforceable rights to prison jobs and training, bars prisoners from collecting damages relating to lost prison jobs and training caused by the alleged breach of a settlement agreement by prison officials. The ACLU’s State Supreme Court Initiative, alongside the ACLU of Oregon, filed an amicus brief arguing that plaintiff Arnold Huskey, an incarcerated individual whose identity was used in Department of Corrections training materials, is entitled to damages notwithstanding Article I, Section 41(3), because plaintiffs in contract disputes never have to show standalone legal rights to the damages they claim. Instead, they need only show that the damages were reasonably foreseeable consequences of the alleged breach of contract.

Capital Punishment
Menzies v. Utah Department of Corrections
Article I, section 9 of the Utah Constitution protects incarcerated individuals from both cruel and unusual punishment and unnecessarily rigorous treatment. This case asks whether death-sentenced plaintiffs seeking to challenge certain execution methods as cruel and unusual or unnecessarily rigorous under this provision must identify, in their pleadings, an alternative method of execution. The U.S. Supreme Court has required this alternative for Eighth Amendment challenges, but the ACLU’s State Supreme Court Initiative, alongside the Capital Punishment Project and ACLU of Utah, filed an amicus brief in support of the plaintiffs, arguing that federal caselaw does not limit the greater protections provided by section 9 of the Utah Constitution. Forcing prisoners challenging a method of execution to identify an acceptable alternative method is cruel, coercive, and not necessary to the administration of Utah’s death penalty laws.
